Excel连接pipe理器的EzApi问题

EzApi是用来创buildSSIS包的，包通过oledb连接pipe理器读取excel文件（microsoft.ace.oledb.12.0）当我在读取excel文件的数据stream之后创buildEzExecSQLTask对象时，

我得到了exception： object does not match the target type

在debuggingEzApi代码后，我发现下面一行是生成exception

host.Properties["TimeOut"].SetValue(host, value);

似乎当属性通过reflection设置时，它不会find目标对象。

代码在widows xp机器上工作正常，但在Windows Server 2012上造成这个问题。

当microsoft.ace.oledb.12.0用于连接到excel文件时，仅在Windows Server 2012上发生问题。 相同的代码在microsoft.ace.oledb.12.0 32位驱动程序的窗口XP中正常工作

请帮助….我们可以进一步移动。
